ABSTRACT OF THE DISCLOSURE A textile spinning frame including apparatus for automatically dofiing and donning bobbins and, if desired, for rejoining breaks occurring in a strand of yarn. A carriage passes the numerous spinning positions on the frame and automatically delays its travel to service any spinning position requirnig attention.

INTRODUCTION This invention relates to the field of textile spinning frames for processing staple fibers and is concerned more particularly with an automatic tender for such frames.

Although modern spinning frames have been developed to a high level of efficiency, they are not yet capable of running without interruption between bobbin changes. Thus, studies have been shown that an average of 20-30 ends down per 1,000 hours of spindle operation can be expected. While this number is relatively small, it is sufficient to require the pressence of an operator to perform the delicate operation of piecing up the down end to restore the spindle to production. The need exists, therefore, for a mechanism adapted to carry out this operation automatically and, incidentally, to dotf such bobbins as are fully wound, don empty bobbins and initiate spinning on the new bobbins.

One object of the present invention is to provide an apparatus for travelling cyclically along one or more spinning frames and returning to production those spindles which are inoperative because of a broken end.

Another object of the present invention is to provide an apparatus capable of doffing a wound bobbin from the spindle of a spinning frame.

Another object of the present invention is to provide an apparatus capable of placing an empty bobbin on a spindle of a spinning frame and initiating winding thereon.

Another object of the present invention is to provide an apparatus capable of randomly dofiing a wound bobbin from a spinning frame while avoiding the necessity of halting the operation of the remaining spinning stations of the frame.

A further object of the present invention is to provide an apparatus capable of automatically reuniting the outer yarn end on a take-up package with its companion end flowing from a roving supply.

Still a further object of the present invention is to provide apparatus capable of rejoining the outer end of yarn of a take-up package on a spinning frame with its companion supply end at a spinning station of a textile frame, and automatically reinstituting the normal spinning and winding cycle thereof.

A further object of the present invention is to provide apparatus capable of moving a free strand end along a predetermined path while imparting twist thereto.

Yet, another object of the present invention is to provide apparatus capable of automatically .threading a strand through the traveller of a spinning frame.

Still, a further object of the present invention is to provide apparatus capable of returning to production those spindles of a spinning frame which are inoperative because of broken ends wherein the supply end is automatically connected to the take-up means while being twisted.

An additional obiect of the present invention is to provide apparatus for repairing a break occuring in strandular material being processed on a textile machine, and including means for sensing said break and for sensing the failure of such repair procedure.

Other more specific objects and advantages will be apparent from the following detailed description when read in conjunction with the appended drawings in which:

FIG. 1 (Sheet 1) is a front elevation of a section of a spinning frame equipped with one embodiment of the apparatus of this invention, only enough of the frame components being shown as to convey the manner in which the invention is associated therewith, certain parts being cut away or omitted for clarity;

FIG. 2 (Sheet 2) is a transverse cross-section of the apparatus of FIG. 1 taken substantially along line 2--2 of FIG. 1 with some parts omitted or cut away, again for sake of clarity;

FIG. 3 (Sheet 3) is an enlarged detail view of the subcarriage assembly shown in side elevation somewhat similar to FIG. 2.

FIG. 4 (Sheet 4) is a perspective view of the carrier registering mechanism of the invention, the carriage lock actuating mechanism being omitted for lack of space;

FIG. 5 (Sheet 4) is a front elevation of the mechanism of FIG. 4 including the actuating lever and solenoid;

FIG. 6 (Sheet 4) is an enlarged detail view looking down on a portion of the bobbin magazine in FIGS. 1 and 2 showing the magazine gate;

FIG. 7 (Sheet 5) is an enlarged detail view of the driving connection for the bobbin transport arm;

FIG. 8 (Sheet 6) is a view greatly enlarged of a portion of one of the suction vortex nozzles of the invention shown partially in section and partially in side elevation;

FIG. 9 (Sheet 6) is a plan view looking down on the nozzle element of FIG. 8;

FIG. 17 (Sheet 7) is an enlarged view in perspective of the ring traveller threading mechanism;

FIG. 18 (Sheet 7) is a perspective view of a fragment of the mechanism of FIG. 17 taken from a different direction and showing such mechanism as it first makes contact with the yarn being threaded;

FIG. 19 (Sheet 7) is an augmented view similar to FIG. 18 showing an intermediate stage of the mechanism;

FIG. 20 (Sheet 4) is a plan view looking down on the mechanism of FIGS. 18 and 19 showing the final operative stage thereof with the traveller engaged on the yarn;

FIG. 21 (Sheet 3) is a perspective view similar to FIG.
